A buddy of mine recently installed LEDs in his Cobalt (plate and trunk). Now I'm totally sold on the idea. Besides looking good, the trunk light provides more light than the stock bulb that was there. I've been looking at what different vendors have to offer this week. Of course they all say that they have the best, brightest ect... I don't think all LEDs are created equal so... is there anything special to look for when purchasing these bulbs. Also, after seeing the color of the plate bulb, some 6000k hids would be a nice match!
Oh and one other thing, the site that the OP lists above, they list LED fog light bulbs. Never thought about using them in the fogs. What do you think?
